I’ve installed eM Client V6 on 9 Machines.
1st problem that occurs is that eM Client doesn’t find the client’s Exchange server. I enter the clients emails, password and it finds the exchange client of a neighbouring company on a different subnet. Given me that the credentials for the server are wrong and no way to change the server address.
But I’ve gotten past that. Told eM Client the email address is firstname.lastname@example.org and it told me it can’t find the server, then I manually told him where the server is - in this case, 192.168.2.3 - and it adds the mail and the mailbox fine. It downloads all the mails as well.
2nd problem encountered is that the account won’t send out any mails. The error is displayed as such:
9:49:04 MailExceptions.OperationException: Sending email failed with an error: The user account which was used to submit this request does not have the right to send mail on behalf of the specified sending account. —> Microsoft.Exchange.WebServices.Data.ServiceResponseException: The user account which was used to submit this request does not have the right to send mail on behalf of the specified sending account.
The exchange server also has DNS service on it and all the computers in the company are connected to the server and are in the local domain.
The user logging onto the computer is User1, but uses email address belonging to User2. In Exchange Maintenance Console, User1 has Full Access/Send As permissions for User2 - in Outlook, that’s enough to send mail as another user.
In eM Client however, that doesn’t appear to be enough.
The client receives the mails without a hitch, outgoing get stuck with that message.
I’ve turned on the logging for the EWS services and sent the logs to Paul McGregor on eM staff.
P.S.: There seems to be numerous other topics open with the same problems described, but I’m creating a new one as per instruction by earlier mentioned customer support persona.
